Apache only recognize one domain..

Hi.!! I had created some webpages for a couple of friends, and I decided to get a dedicated (A fortatrust promotion $10) so I can manage them myself..
The server came with CentOS 6, apache and Mysql preinstalled, so I just had to install webmin, the ftp users, and the virtualhost as follow:

(The spaces in the web adresses are due to the forum policy, they dont exist in the real file)

After that, I restart the apache.. then, in Godaddy, I forwarded the domains to my server IP, but It doesnt matter wich of the 3 web addresses I type, it always take me to the webpage1, so I got a couple of questions:
Do I need to set up something more, for apache to handle the virtualhosts..?
Ist better to forward the domains or to redirect to a NS address..?
In order to create a NS address in my server, I need to install BIND or it can be done in other way?
Thanks in advance for all your help..!!
